Combi Pilot light trouble - again!!

[Elliot]

have a Puma 80, its about 6 yrs old. It got a new PCB 6 months ago because pilot light was going out all the time so it was fixed with that.

Now the pilot light is going out again, but this time there is no banging of pipes when pilot light goes off like before. like before it goes out when HW is used.
The boiler sounds much different to last time it does not sound the boiler is boiling dry it just sounds normal with pump going.

Can any one give me any idea's on what this problem is this time surely not the PCB again, well it was apparently a relay sticking on boiling water dry so over heating. Could it be the HW sensor switch sticking.

get it out and fit a Baxi 80 eco,they are £500 and should be able to get it fitted for £200-£250,The puma's and combi 80's are nowt but problems and you'll spend a fortune on it.I don't recomend anyone who is not competent and gas trained to even take the cover off any gas appliance.
